For operation of spherical bushing unit
(1) Assembly and fixing mathod of unit
- insert the unit at the specified position of the shaft.
- Fix the inner ring and the shaft with set screws.
- Fix the case with bolts.
- Make sure that the mating part for the unit is suitable for operating conditions.
- Be careful that there is no foreign matter or step on the mounting surface.
- When three units or more are used, align the shaft correctly.
(The tolerance should be +/-0.25 mm.)
(2) Fixing method of shaft and inner ring
Fix the inner ring at the position where the flange does not come in contact with the outer ring and. Fix it with the Clearance of 0.1 mm as a guideline. If interference between the inner ring flange and the outer ring end due to thermal expansion/shrink of the shaft is concerned, adjust the clearance appropriately. (One straight type screw per position is used)
if the unit is used at a plece or environment where vibration or impact is applied, provide seating at the set screw Position of the shaft with a file or borer.
(3) - For thrust load
If thrust load is applied, use the flange type inner ring. Solid lubricant is embedded at one side of the outer ring.
When a flange type is used, make assembly so that the flange area may match the solid lubricant surface at the side.
(4) - For greasing
Grease groove is provided at the outer ring. Greasing can improve wear résistance and durability.
